Multi-objective Optimal Kinematic Synthesis of Cam Profiles for Engine Valve Trains
Kinematic cam profile synthesis for engine valve trains to satisfy the requirements of a large lift area and small acceleration magnitudes is a multi-objective optimization problem. This paper proposed that its Pareto optimal solution set is constructed with constant acceleration profiles. For the definite design of an engine valve train, its Pareto front is a function of the time durations of the positive and negative accelerations. The relationships of positive acceleration, negative acceleration, and lift area for a constant acceleration cam profile are analyzed, and the results are applied to discuss the characteristics of polynomial cam profiles.
